The Lowdown

Alright, let’s get into it.

The first week is shaping up to be the main event here, no doubt. We’ve got some solid, clean south swell pushing through, and the conditions are lining up much better than the second half of the window. If you can get out between Sunday and Thursday, you’re going to score. Things get a bit ordinary and small after that, so make the most of the first few days.

We start things off proper on Sunday morning. Jaconé (Costa Rica) is seeing a clean 7ft SW groundswell out of the SSW at 14 seconds. There’s a light offshore breeze and the water temp is sitting about average for this time of year. The energy is strong, with a combined reading of 1556, and it’s going to be glassy and clean. This is solid, powerful surf for the experienced crew. It’s a bit much for beginners, honestly, at this size. The break is exposed and consistent, and the crowd might be there on a Sunday, but the waves will be worth it. Afternoon gets a bit messier with onshore wind, so stick to the morning.

Monday keeps the good times rolling. Morning is a bit cross, but there’s still a decent 7ft S swell at 12 seconds. Energy remains strong at 1378. It won’t be as clean as Sunday, but it’s still very surfable. The afternoon, though, jumps up to 8ft and gets choppy with a cross-onshore breeze, and the score drops. Better to be out early.

Tuesday is a standout. Morning has that S swell at 8ft, 13 seconds, with a clean cross-offshore wind. The energy is pumping at 1759, and the surf is excellent for experienced surfers. The afternoon is even better, pushing 8ft with a similar period, and it’s still looking clean. This is probably the best day of the whole stretch for size and quality combined. Crowds are possible, but for waves like this, you deal with it.

Wednesday is still firing. Morning sees a 7ft, 12-second S swell with a true offshore wind – that’s a major positive. It’s clean, glassy, and the energy is still moderate-strong at 1369. The afternoon stays at 7ft but the wind picks up a bit. Still good, but the morning is the pick.

Thursday morning is another clean one. The swell is easing a touch to 6ft, but it’s still from the S at 12 seconds. Light offshore wind makes for clean conditions, and the energy is at 1054. It’s a fun, powerful size for intermediate-to-advanced surfers. The afternoon drops a bit to 6ft but stays clean.

Then we hit a bit of a lull. Friday sees onshore winds and the quality drops right off. Don’t bother. Saturday keeps that onshore flow and adds a lot of wind, too, making it messy.

The second week is a much quieter story. From Sunday the 16th, the swell drops away significantly. We’re looking at mostly small, short-period windswell in the 3-5ft range, with a lot of those days not offering much quality. There’s a bit of a gap where it’s just not worth paddling out. The energy readings drop from the strong 2000s we saw earlier down to the low hundreds, which tells you everything.

Tuesday the 18th has a brief moment of glassy conditions early, but the swell is small and weak. It’s more of a longboard or funboard day, and even then, it’s pretty marginal.

We do see a slight pulse of S groundswell on the 21st, but it’s tiny – under 3ft. And there’s an attempt at a better S swell arriving on Monday the 24th, showing 5ft at 12 seconds with an offshore wind. That one looks promising, but it’s a long way out, so treat it as a hope rather than a certainty. It’s the only real light in an otherwise flat and weak second week.

So, the takeaway: get out there from Sunday to Thursday. Tuesday morning and afternoon are the absolute standouts – big, clean, powerful surf. The rest of the window is mostly small, weak, and not worth getting excited about. The water is about average for this time of year, and that first week is going to be memorable.

Information about the Jaconé Surf forecast

The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
